DE or IANA: Who Has the Final Say?

Hey folks! Let's dive into a bit of a head-scratcher related to the ietf-wg-mediaman working group (and the broader 6838bis world). We've been wrestling with a particular sentence, and it boils down to this: Who gets to approve changes? Is it the Designated Expert (DE) or the Internet Assigned Numbers Authority (IANA)? This is a critical question because it affects how we manage and evolve standards. Let's break it down and see if we can get to the bottom of this. This is important stuff, so pay attention!

The Core of the Matter: Change Control

At the heart of our discussion lies change control. The specific text we're looking at (after some editorial tweaking, of course) states:

Changes may be requested by the change controller, or by other parties if the Designated Expert(s) verify that the change controller approves the change.

Now, this seems pretty straightforward, right? But the key question here is: What role does the DE really play in this process? Does the DE have to actively approve every single change, or is their role more about verifying that the change controller is okay with it?

Think of it like this: Imagine you're building a house. The change controller is like the project manager. They're the ones ultimately responsible for making sure everything fits together. The DE, in this scenario, could be the architect or a senior engineer. They need to ensure that any proposed changes align with the overall design and don't compromise the structural integrity. The IANA, then, is like the city permitting department. They make sure everything follows local laws and regulations.

So, the core issue here isn't who requests the change (that's flexible), but rather who gives the thumbs up. Is it a DE sign-off or an IANA blessing?

Understanding the Roles: DE vs. IANA

Let's clarify the roles of the Designated Expert (DE) and the Internet Assigned Numbers Authority (IANA). Understanding their respective responsibilities is crucial for figuring out who's in charge of approving changes. Remember, this isn't just about semantics; it impacts how quickly and efficiently we can update and improve standards.

  • Designated Expert (DE): The DE is typically a subject matter expert with a deep understanding of the technical details and implications of changes. Their primary role is to ensure the changes align with the technical specifications, maintain interoperability, and don't introduce any unforeseen issues or conflicts. They act as a technical gatekeeper, verifying the validity and impact of proposed changes. They are like your local tech guru, making sure everything works smoothly.

  • Internet Assigned Numbers Authority (IANA): IANA is responsible for the allocation and management of a wide range of Internet protocol parameters, such as port numbers, protocol numbers, and other identifiers. Their role is to ensure these resources are allocated consistently and without conflicts, guaranteeing the smooth functioning of the Internet. Think of IANA as the central registry, ensuring everything has a unique ID and plays nicely with others. They are the keepers of the keys!

So, in the context of change approval, the question becomes: Does the DE's expertise extend to approving the changes, or do they primarily validate them, ensuring they're technically sound? And if the changes involve resource allocation, does IANA need to be involved in the approval process as well?

Analyzing the Text: What Does it Actually Mean?

Let's go back to the text and analyze it carefully. The phrase "the Designated Expert(s) verify that the change controller approves the change" is where the crux of the issue lies. Does "verify" imply approval? Or does it simply mean the DE checks to ensure the change controller (the person responsible for the process) has given the green light?

Here are a few possible interpretations:

  1. DE Approval: The DE has the final say. They independently assess the change and approve it, perhaps after the change controller has already given their consent. This places significant responsibility on the DE, potentially slowing down the process, but ensuring a high level of technical scrutiny.
  2. DE Verification of Change Controller Approval: The DE's primary role is to verify the change controller's approval. This suggests the DE ensures the change aligns with technical standards and doesn't cause any problems but doesn't necessarily have the power to block a change already approved by the change controller. This is like a second opinion. This scenario is likely what the text is leaning towards.
  3. IANA Approval (in specific cases): If the change involves the allocation of resources managed by IANA, IANA might need to give their approval as well. This is especially true for changes impacting things like port numbers or protocol identifiers. IANA acts like the registry.

Ultimately, understanding the intent behind the wording is critical. What were the authors trying to convey? Was the goal to give the DE the power to independently approve changes, or was it a way of making sure changes went through the official channels?

The Implications: Speed, Expertise, and Control

How we interpret this text has serious implications for the efficiency of the standards process. Let's think about the different scenarios and their consequences.

  • If the DE has ultimate approval authority: This approach provides a high level of technical rigor. Changes will be meticulously vetted by experts. The flip side is that it can slow down the process, potentially delaying important updates and improvements. This is good for high-stakes changes, but can slow down the smaller ones. There's a trade-off.

  • If the DE verifies the change controller's approval: This option could be faster. The DE's expertise is still utilized, but they don't have absolute power. This would allow the change controller to move more quickly, assuming the technical experts find no flaws with the changes. This can also increase agility and responsiveness to emerging issues. That's a huge win.

  • If IANA gets involved: This is crucial when changes affect resource allocation. If IANA doesn't approve, the whole thing grinds to a halt. This ensures that the Internet’s resources are allocated without conflicts and that things continue to work correctly.

Therefore, we have to consider these trade-offs. The goal should be to find a balance between thoroughness and efficiency, ensuring that changes are technically sound while not getting bogged down in bureaucracy. It's all about finding the perfect mix.

Finding Clarity: What's the Solution?

So, how do we get some clarity? Here's what we need to do:

  1. Consult the Intent: We need to go back to the original authors or the relevant working group documentation to understand the original intent of the text. What were they trying to achieve?
  2. Define Roles Clearly: If the roles are not clearly stated, we have to create them, defining the responsibilities of the DE, the change controller, and IANA. Avoid ambiguity! Clear definitions are the key.
  3. Revise the Text: Based on the clarified roles, we may need to revise the text to be crystal clear. The more explicit, the better. This could involve changing "verify" to "approve," or adding clarifying phrases to spell out the approval process.
  4. Consider the Context: Does the change impact resource allocation managed by IANA? If so, IANA needs to be involved. This requires coordination.

By taking these steps, we can ensure the change control process is clear, efficient, and consistent, benefiting everyone involved in developing and maintaining Internet standards.

Conclusion: Who Wins?

So, who really has the final say, the DE or IANA? Well, it depends! It depends on the specifics of the change, the technical implications, and the role of the change controller. In most cases, the DE likely verifies the approval of the change controller to ensure technical soundness, and IANA gets involved when resource allocation is affected. It’s a team effort, guys!

Ultimately, the goal is to make sure we strike the right balance between technical excellence and efficiency. By clarifying the roles, understanding the intent, and making sure the text clearly reflects the process, we can keep the internet's standards evolving smoothly. Let's keep those changes coming, and make the internet the best it can be! Now, go forth and be excellent to each other!
